Two legacy codes can normalise to the same label (eu_west and eu-west), and
separate counters then handed both of them eu-west-01 — a unique-constraint
failure inside the reservation, which blocks onboarding rather than being a DNS
problem the step can shrug off. Lock, counter and the in-use check all key off
the label now.
(The helper was also called label(), which HostStep already declares as the
step's display name — renamed.)

alpha_dash accepted eu_west, -edge and edge-, none of which are valid DNS
labels — every host in such a datacenter would have failed registration and,
because DNS is non-fatal, silently ended up without a name. The console now
requires a proper label, and the step normalises anything created before that
rule so existing rows still get a usable name.

Codex was right that my never-reuse claim did not hold:
- The lock was released with only a candidate in hand, so two concurrent
onboardings in one datacenter could pick the same name and overwrite each
other's record. The name is now persisted on the host while still locked.
- The number was derived from the hosts that happen to exist, so removing the
highest one handed that number straight back out — a cached name would then
resolve to a different machine. The counter is stored per datacenter, floored
by what is actually in use so a wiped settings store cannot reissue live names.
- PurgeHost deleted the row that carried the record id, leaving the machine's
management address published with nothing left to clean it up.

fsn-01.node.clupilot.com, numbered per datacenter and never reused — removing a
host must not renumber its neighbours onto its name, so the number is stored
rather than derived.
The record points at the host's WireGuard address, not its public IP: the name
exists so an operator can reach a host by name over the VPN, and publishing a
Proxmox host's public address would hand every scanner a target, which is the
one thing this network design avoids.
DNS is convenience, not a prerequisite: a failure logs an event and lets the
onboarding finish rather than stranding a host that is otherwise ready.
